Reps are performed like the song "12 Days of Christmas." It will look like this: 1 thruster, then 2 snatches + 1 thruster, 3 S2OHs + 2 snatches + 1 thruster, 4 power cleans + 3 S2OH + 2 snatches + 1 thruster...(1, 2+1, 3+2+1, 4+3+2+1, 5+4+3+2+1, 6+5+4+3+2+1...). The numbers in the parenthesis are the sum of the reps of that movement after the completion of the WOD.
